Description
Cette invention concerne un produit ainsi que son procédé pour obtenir une isolation coupe-feu.This invention relates to a product and its method for obtaining fire insulation.
Selon la technique connue en particulier à bord des navires où l'isolation coupe-feu des ponts et des cloisons est obligatoire, l'isolation est obtenue par des panneaux en matériau isolant.According to the known technique especially on board ships where the insulation Firewall bridges and bulkheads is mandatory, the insulation is obtained by panels of insulating material.
L'application des panneaux en ce matériau, selon la technique connue, comporte néanmoins plusieurs inconvénients.The application of panels made of this material, according to the known technique, nevertheless has several disadvantages.
Puisque ces panneaux connus ne sont pas rigides et ne peuvent être piétinés, ils ont le grave inconvénient qu'il est nécessaire de les poser sur la face inférieure des ponts ou sur un côté des cloisons étanches et les fixer avec des aiguilles à la structure qui doit être isolée; ces aiguilles, à cause de leur soudure interrompent le cycle de peinture anticorrosion, en outre elles constituent des points de conduction de la chaleur et elles limitent donc les caractéristiques d'isolation de ces panneaux.Since these known panels are not rigid and can not be trampled, they have the serious disadvantage that it is necessary to on the underside of the decks or on one side of the watertight bulkheads and fix them with needles to the structure that must be insulated; these needles, because of their welding interrupt the painting cycle anticorrosion, in addition they constitute conduction points of the heat and they therefore limit the insulation characteristics of these panels.
Un autre inconvénient de ces panneaux connus est dû au fait qu'ils doivent être interrompus au niveau de tout élément de renforcement de la structure. Par exemple dans les navires, il y a des éléments faisant saillie de la surface inférieure des ponts, tels que les poutres renforçant la structure et les installations techniques comme la tuyauterie et les faisceaux de câbles fixés par des brides au plafond des locaux. Ces éléments en saillie doivent donc être recouverts successivement par un revêtement isolant pour assurer l'isolation coupe-feu continue comme désiré.Another disadvantage of these known panels is due to the fact that they should be interrupted at any level of reinforcement the structure. For example in ships, there are elements making protruding from the lower surface of bridges, such as reinforcing beams structure and technical facilities such as piping and cable bundles fixed by flanges to the ceiling of the premises. These protruding elements must therefore be covered successively by one insulating coating to ensure continuous fire insulation like longed for.
De plus, étant donné que, selon la technique connue, le matériau isolant doit couvrir les structures métalliques auquelles ils sont fixées par des brides, telles que les gouttières porte-câbles, conduites d'aération et tubulures et, puisque toutes ces installations sont aménagées successivement, montées, démontées, comprimées, elles entravent souvent la mise en oeuvre des panneaux isolants causant des ruptures et des réfections. Tous ces inconvénients exigent un emploi plus grand de main d'oeuvre, et ils sont cause de pertes de temps et donc de coûts plus élevés.In addition, since, according to the known art, the insulating material shall cover the metal structures to which they are attached by flanges, such as cable gutters, ventilation ducts and tubing and, since all these facilities are successively, mounted, dismantled, compressed, they hinder often the implementation of insulating panels causing breaks and repairs. All these disadvantages require a greater use manpower, and they are a waste of time and therefore costs higher.
Un autre inconvénient des panneaux connus est la suspension de fibres qui resteront quelque temps dans le milieu de travail, libérés par la coupure des panneaux au cours de leur mise en oeuvre, pour les adapter à la structure à revêtir.Another disadvantage of known panels is the fiber suspension who will stay for a while in the workplace, released by the cutting of the panels during their implementation, for the adapt to the structure to be coated.
Du Brevet US-A-2993016 est déjà connu un produit pour une isolation coupe-feu constitué de plâtre, de vermiculite ou perlite expansée et d'additifs. Selon certains exemples de réalisation, on trouve la présence d'amiante.From US-A-2993016 is already known a product for an insulation firestop consisting of plaster, vermiculite or expanded perlite and additives. According to some embodiments, we find the presence of asbestos.
Tous ces inconvénients ont été éliminés par le produit et le procédé d'application de cette invention tel que définis par les revendications annexées.All these disadvantages have been eliminated by the product and the process application of this invention as defined by the appended claims.
Cette invention a le but de réaliser un enduit ou bien une couche piétinable, ayant les caractéristiques prévues d'isolation coupe-feu.This invention has the purpose of producing a coating or a layer footprint, having the expected characteristics of fireproof insulation.
A ce but, un produit a été étudié apte à fournir un enduit léger et incombustible qui puisse bien adhérer à des supports en acier, tôles galvanisées, aluminium, ciment, bois, faésite, plâtre etc.For this purpose, a product has been studied capable of providing a light coating and non-combustible that can adhere well to steel supports, sheet metal galvanized, aluminum, cement, wood, faesite, plaster etc.
Le produit objet de cette invention offre maints avantages tels que les
suivants:
L'application est beaucoup plus facile qu'avec les panneaux connus, par example lorsqu'il s'agit des ponts des navires, parce que le produit fini forme un platelage qui peut être appliqué sur la surface du pont et ses caractéristiques de poids et épaisseur sont comme ceux des produits connus ordinaires.The application is much easier than with the known panels, by example when it comes to ship decks, because the finished product forms a decking that can be applied to the deck surface and its weight and thickness characteristics are like those of the products known ordinary.
La mise en oeuvre du produit selon cette invention est absolument indépendante des installations, elle ne cause aucun obstacle ni des chevauchements comme ceux déplorés dans l'application de la technique connue, mais elle permet un travail facile simultané.The implementation of the product according to this invention is absolutely independent of the installations, it does not cause any obstacle or overlaps like those deplored in the application of the known technique, but it allows easy simultaneous work.
Un autre avantage est de nature économique car la mise en oeuvre est facile et parce qu'il ne faut pas retourner au travail déja fait pour le rétablir et/ou pour des retouches successives.Another advantage is of an economic nature because the implementation is easy and because we must not go back to work already done for the restore and / or for successive retouching.
Un autre avantage du produit selon l'invention c'est qu'il n'offre pas seulement une protection contre le feu, mais a aussi des caractéristiques d'insonorisation et qu'il peut être appliqué sur les parois.Another advantage of the product according to the invention is that it does not offer only a fire protection, but also has features soundproofing and that it can be applied on the walls.
Le produit objet de l'invention n'est pas seulement incombustible, mais il offre aussi les avantages: d'être inerte, imputrescible, parfaitement résistant aux moisis et bactéries et qu'il y a aucun danger ou risque pour l'ouvrier.The product object of the invention is not only incombustible, but it also offers the advantages: to be inert, rot-proof, perfectly mold and bacteria resistant and there is no danger or risk to the worker.
Le procédé d'application du produit de cette invention peut être le suivant : The method of applying the product of this invention may be as follows:
Les surfaces de la structure qu'il faut isoler doivent être prétraitées avec un convenable produit promoteur d'adhésion anticorrosif, elles doivent être sans graisse, huile, poussières et/ou matières souillantes. Avant le complet séchage du produit promoteur d'adhésion, il faut appliquer une couche du mortier comme décrit ci-dessus, sur lequel est appliqué un filet en fibre de verre qui doit être recouvert par une autre couche du mortier selon cette invention.The surfaces of the structure to be insulated must be pre-treated with a suitable product anticorrosive adhesion promoter, they must be free of grease, oil, dust and / or soil. Before the complete drying of the adhesion promoter product, it is necessary to apply a layer of the mortar as described above, on which is applied a fiberglass net that must be covered by another layer of mortar according to this invention.
Après le séchage du mortier, la surface peut être refinie avec des produits de revêtement (moquette, vinyle etc.) ou avec des produits imperméabilisants ou encore embellie par des peintures communes.After drying the mortar, the surface can be refinished with coating products (carpet, vinyl etc.) or with products waterproofing or embellished with common paints.
